What are the prohibited moves that result in an automatic loss?

Grabbing the front section of the belt, or sticking one’s fingers in and pulling.

Grabbing the throat

Kicking the stomach or chest

Bending back one or two fingers

In official tournaments, you will almost never see any of these moves. There have been cases, however, of pulling top-knots and grabbing at the front of belts. The main basis for judgment is whether the gyoji and judges feel the move was intentional, although they do not confer with the rikishi involved on this point.
